The distributor will release the film in September.

Based on the acclaimed book History on Trial: My Day in Court With a Holocaust Denier, the film chronicles Deborah E. Lipstadt’s (Weisz) legal battle for historical truth against David Irving (Timothy Spall), who accused her of libel when she declared him a Holocaust denier.

Mick Jackson (Temple Grandin) directed Denial from a screenplay by David Hare (The Reader).

The drama, which also stars Tom Wilkinson, is being produced by Gary Foster and Russ Krasnoff. Participant Media’s Jeff Skoll and Jonathan King are executive producing alongside BBC Films’ Christine Langan and Joe Oppenheimer. Bleecker Street’s Andrew Karpen and Shoebox Films' Guy Heeley also are executive producing.

Denial will face off against five wide releases on Sept. 30: Lionsgate/Summit's Deepwater Horizon, STX Entertainment's The Edge of Seventeen, High Top Releasing's Incarnate, Relativity's Masterminds and Fox's Miss Peregrine's Home for Peculiar Children.

Denial will follow in the footsteps of Bleecker Street's Cannes hit Captain Fantastic, which is set to open July 8.
